Abstract:

A circuit for linearizing the oscillator sweep output frequency signal of a voltage controlled oscillator is disclosed. The voltage controlled oscillator is driven by the output of an op amp, which amplifies and filters the output of a DA converter. The DA converter responds to preselected 8-bit words, stored in an eprom, so as to produce a desired output frequency at each memory address. The addresses, in turn, are provided by a combination of gates, counters, input signals and a clock.
